Brake pedal is sticking

A month ago I noticed my brake pedal would stick when I turned into my driveway, well then I would here a grinding sound coming from my tires. I was on the home from work yesterday when all of sudden my steering wheel started shaking vigorously like my tires were about to fall off. So I finally made it home, and this morning when I got ready to leave my car started making this loud popping sound, and then it felt like my wheels were locking up, so I just parked it and drove my wife's vehicle. What could this be?
